DisplayLink Drivers and J5Create Drivers

[bdushok]

I've recently purchased a USB-C hub from J5Create. I installed the driver for this device, not realizing it was only for video. I'm using a DisplayLink device and did not plan to use video from the hub.

Since installing the J5Create drivers the monitors connected to my DisplayLink adapter perform very slowly. Moving a window, for example, over one of these monitor show very choppy.

I've tried uninstalling the J5Create drivers using the shell script they provided, no improvement.

I uninstalled DisplayLink and installed the latest version. Again, no improvement.

I discovered the J5Create uninstall shell script left a system extension named Triggers running. I disabled SIP and used systemextensionsctl to remove it. Again, no improvement.

I tried reinstalling DisplayLink again. No improvement.

Does anyone have any suggestions on how I can correct this problem?

Thanks,
Bob
